The Claim
A beverage containing at least 0.75% glycerol and at least 15 mM sodium reduces body mass loss over 210 minutes more effectively than a placebo in healthy, active adults, indicating improved fluid balance.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Drinking a beverage with at least 0.75% glycerol and at least 15 mM sodium results in less body mass loss over 210 minutes compared to a placebo in healthy, active adults, indicating better retention of fluids.
See the scientific wording
Combining at least 0.75% glycerol with at least 15 mM sodium in a beverage improves fluid balance in healthy, active adults more than placebo, as shown by smaller reductions in body mass over 210 minutes.
When a person drinks a beverage with glycerol and sodium, these substances enter the blood and make it more concentrated. This signals the brain to reduce the release of a hormone that tells the kidneys to pee out water. With less of this hormone, the kidneys hold onto more water and send it back into the bloodstream instead of letting it leave as urine. This keeps more fluid in the body and prevents weight loss from water loss.
What the research says
1 studyThis study found that a drink with just a little glycerol and a little salt helped people keep more water in their bodies than plain water, exactly as the claim says.
